System-level software virtualization is commonly employed in virtual hosting environments, where it is useful for securely allocating finite hardware resources amongst a large number of users and their respective applications. System administrators may also use virtualization, to a lesser extent, for consolidating server hardware by moving services on separate hosts into software entities referred to as containers, for example. In general, system-level software virtualization provides a method where the kernel of an operating system allows for multiple isolated user space instances, instead of just one. Such instances such as containers, virtualization engines (VE), or virtual private servers (VPS), for example, may operate like a monolithic server from the point of view of its owners and users yet at the same time is virtualized to a much smaller server footprint via available container technologies.
